Brazil has a very complex tax system, with significant amount of taxes (many focusing on the same taxable fact) and ancillary obligations - at all levels of government - and which constantly undergo changes, repeals and innovations. In the face of such tax dynamics, it is very common that companies have doubts concerning the correct application of tax practices, resulting in excessive legal uncertainty. In addition, the misunderstood tax law, and its consequent application, can lead to formation of a tax liability, which in many cases is not known by the company. In order to minimize the tax risks, it is appropriate that the company conducts a tax study about its current practices and whether they nurture maximum tax efficiency to the company. Therefore, Vallya proposes a preliminary study aimed at identifying the tax practices that the company uses in is operational routine, and if these are the most efficient. After a careful analysis, our consultants will present the results and suggest the best alternative to minimize risk and follow best practices.
